# Advertisement of Prospectus (Section 30)
## What does the section regulate?
When a company publishes an advertisement of its prospectus (newspaper, periodical, electronic media etc.), the advertisement is a short-form invitation to the public. To prevent misleading 'teaser' ads, the section mandates that certain contents from the Memorandum of Association be reproduced.
## Mandatory contents in the advertisement
The advertisement must specify:
1. Objects of the company (from Memorandum).
2. Liability of members AND the amount of share capital of the company.
3. Names of the signatories to the Memorandum.
4. Number of shares subscribed for by the signatories.
5. The company's capital structure.
## Why these five?
They collectively answer four investor questions:
- What does the company do? (Objects)
- How much skin in the game do members have? (Liability + capital)
- Who founded it? (Signatories + their subscription)
- How is capital structured? (Capital structure)
